Annabeth 's POV

When I open my locker, a piece of paper falls onto the floor. I pick it up.

Hello. You haven't a clue. But I do. Here you go: I kill kings, make mountains crumble, and make all life come to an end. What am I?

Tick tock. The clock is ticking. PS. Library.

"What the heck?" I say as I read the note. "Library?" I check my phone. 12:01. Lunchtime. I grab my lunch and head to the library. Hey, it said library. Don't judge!

"Kills kings, makes mountains crumble, makes everything living stop. Man that's weird. Well an assassin kills kings, but it doesn't do much else. And wind and erosion makes mountains crumble. What makes everything living stop?Hmmmm."

I pondered the the riddle for a minute. "Tick tock? Clock is ticking... Speaking of clocks what- it's TIME! Time kills kings. It makes mountains crumble. And it makes everything living stop! But why library? Could it be the clock or something? Maybe a book about time." I look around the shelves for something about time. Bingo! I pull the heavy book labeled TIME from the shelf. Must've been too obvious because there's nothing inside. Maybe the clock. I open the glass door of the grandeur old grandfather clock. Nothing.

Then I realize that there's a poster made by the freshmen in shop- of how a clock is made. I dash over to the window where the poster is taped up, and notice a tiny arrow pointing down at the bottom of the poster. I look down, and sure enough, a little piece of paper is stuck under the corner of a table. I pick it up. Just then, the bell rings.

"Crap! That's the end of fifth period! I missed English! Percy is going to kill me for not helping with the project!" I race out of the library, hoping to make it to Science in time.

Percy POV

So it's English. And Annabeth isn't here. And that means I have to this project all by myself today! And I don't even know what it is! I've got it! I'll go and hide in the bathroom for fifteen minutes! Annabeth should be back by then! And then I don't have to do all the work! Good plan, Percy!

I raise my hand. "Mr. Blofis, may I use the bathroom?"

"No, you may not. You might want to remember not to say your 'master plans' out loud next time, Mr. Jackson." Well, shoot. I sulk in my seat.

"Psst, Percy!" Juniper whispers. "The project is about Greek Mythology. Good luck!" She hands me a sheet of paper describing exactly what the project is. I swear Juniper would be nice to Hitler if she met him. Though I suppose that's why Grover likes her.

I'm torn from my thoughts when I find Mr. Blofis hovering over my seat.

"Percy, which Greek gods or goddesses are you and Annabeth debating?" Uhhhh. Crap. Crap. CRAP. I rack my brain for an inkling of any Greek mythology, but to no avail.

"Uhhhh, we hadn't decided yet. They did so many-er- evil things that we couldn't decide which ones were even worth it." I lied.

"Oh, of course. You're completely right, I agree. Did you ever consider Hestia vs Khione? Hearth vs. Ice. That'd be interesting. Or you could expand on the already existent feud between Athena and Poseidon," Mr. Blofis suggests. I know that Athena and Poseidon were two of the twelve main gods, so there'll be more information.

"Hmmmm. I think maybe Poseidon and Athena." I feel kinda bad making the decision without Annabeth, but she had kinda just ditched me to work on it by myself, so I'm not feeling too guilty.

Before I can start working after I read through the instructions, the bell rings. Yeah yeah, I know, I read really slow. It's because I have dyslexia.

Annabeth's POV

When I sat down in Ms. Dove's classroom, I unfurled the note I had found in the library. Another riddle.

This time it was a sudoku puzzle, along with these words: "Solve it. Don't look it up. I'll know if you do, and you'll regret it."
